Heermann’s Birds

One hundred fifty years ago today, Adolphus L. Heermann was killed, “having evidently stumbled and fallen,” when his collecting gun fired.

John Cassin, who knew him well, said of Heermann in earlier, healthier days that no better man could be had for a collecting expedition. In 1853, Cassin dedicated a “beautiful gull” to his friend, an

acknowledgment due to his accomplishment as a naturalist, and his perseverance and success as a scientific traveller.

In Washington, D.C., Spencer Baird was equally impressed by Heermann and his work in the field. On working through a collection of sparrows from the west, Baird encountered one that Heermann had sent from Tejon Pass, California, resembling a song sparrow but

differing very appreciably from a large number of specimens from Washington and Oregon…. I have come to the conclusion that the species is worthy of specific separation, and have accordingly named it Melospiza heermanni, after its accomplished collector and discoverer.

Today we “know” that that California bird is “just” a subspecies of the song sparrow. But there’s no reason not to call it the Heermann’s song sparrow, especially today.

We — or at least I — so often forget about Robert Ridgway as a painter, giving all our attention instead to his talented brother John.

Every time I have occasion or an excuse to use the Baird History, though, I’m struck anew by how sensitive and appealing the plates are that Robert Ridgway painted for the book (some of them under vigorous protest, as Dan Lewis informs us).

Aren’t they lovely?

If you’re not already crazy, thinking hard about Passerculus sparrows will drive you there fast.


The only consolation: greater spirits than ours have been confused by these streaky devils.

Robert Ridgway corrected the labels of the co-types of the San Benito sparrow to read “P. guttatus Lawr.!”

I assume it was the explanation point that rankled. In any event, not long thereafter, Elliott Coues corrected his corrector, adding beneath Ridgway’s notation the words “Scarcely! stet sanctorum–C.”

I don’t know whether the two actually ever sat down to talk about those skins. But each had made his point, loud and clear.



Smelly Sparrows

One of my favorite lines in the history of American ornithology comes from J.P. Giraud‘s description of one of my favorite birds, the Henslow’s sparrow.

Shotgun birders like Giraud found this species no less maddeningly elusive than today’s observers. Happily, though, writes Giraud,

from the eagerness with which it is pursued by dogs, we may infer that it possesses considerable game effluvia.

As late as the 1970s, it seems, hunters in Louisiana were complaining that their dogs were pointing these grassland “stinkbirds” instead of quail.

Gellert, you have a mission.

Song Sparrow

I’ve always assumed that the first description of the vocalizations of the song sparrow was Alexander Wilson’s in the American Ornithology.

The notes, or chant, are short but very sweet, resembling the beginning of the Canary’s song.

I’ve been wrong. A dozen years before Wilson even thought about coming to America, Thomas Pennant in his account of the bird not only mentioned but transcribed the common call in English syllables — not the song, but the call, that familiar husky chirp,

shep, shep.

Pennant, working from specimens sent from the US by Ashton Blackburn, tells us that the bird is

called in New York, the Shepherd, from its note.

Something new, every day.
